7697A Headspace Sampler
7697A Headspace Sampler
必威体育登录手机The 7697A Headspace Sampler is based on Agilent's 7890 GC and 7693A automatic liquid sampler architecture.It provides an inert sample pathway for superior gas chromatography performance without analyte degradation or loss, includes productivity-boosting features, and offers rugged sampling technology to ensure the integrity of every injection.
Automatic leak check ensures each vial is leak-free prior to analysis, with no loss of precision or sensitivity.Hydrogen can be safely used as an alternative carrier gas.Late-arriving important samples can be accommodated with priority sample positions.Barometric pressure compensation results in highly precise and consistent results across multiple labs.

Product Details
Features
- The 7697A Headspace Sampler 12-vial capacity configuration is perfect for academic labs and those with small sample loads
- Standard 111 sample configuration with three priority samples
- Trays can be exchanged during a sequence for increased sample capacity
- Hydrogen carrier and auto sleep/wake modes conserve valuable laboratory resources
- 必威体育登录手机Control through Agilent OpenLab CDS software and Agilent MassHunter software
- Other software control with Waters Empower™ 2 and Waters Empower™ 3 software
- Independent control of vial pressurization and column head pressure provides increased precision by ensuring no back pressure during sample transfer
- Automatic vial leak test checks each vial during pressurization - without time-consuming calibration - to ensure that every sample is properly capped
- Sample bar code reader with data transfer capabilities allows you to track samples before they enter the oven
- Multiple headspace concentrations (MHC) with up to 100 extractions per GC start allows for more complete sampling and increased sensitivity
- Multiple headspace extractions (MHE) with up to 100 extractions per vial
- Supports 10-mL, 20-mL, or 22-mL vials without an adapter
- Method development software transfers methods from any headspace system or quickly designs a method from scratch using just a few known parameters
- Samples depressurize before returning to the tray
- Transfer line interface accessory allows a headspace sampler and ALS to connect to the same inlet on the GC
